When to change image opacity
Opacity adjustment is useful for overlays, watermarks, soft backgrounds, and layered design assets. Lower opacity makes the image more transparent while preserving its shape and details.
Ofte stillede spørgsmål
Why does this tool only download PNG?
PNG supports alpha transparency. JPG does not preserve transparent pixels.
Does opacity change image dimensions?
No. The output keeps the same dimensions as the source image.
Er mit billede uploadet?
No. Your image stays in your browser and opacity adjustment runs locally.
